    • a great little aquarium
This aquarium is very nice for my betta fish and there is a lot of room in this 6 gallon tank for his toys and to swim around in. One change that I made was to remove the filter that came with the tank and put in an AQUANEAT Sponge Filter because they are the best and safest way to filter without hurting the fish. With that, you won't have to worry about your fish getting sucked up into the filter. I did see algae build up on the gravel because the light is very bright, and I discovered that you can reach up to the round light and easily rotate it around in order to dim the light. It is so easy and helpful. I'm glad that I noticed this because now I get no algae and it is a perfect tank. ... show more

Very pretty. Plenty of room for my snails and little crab. Beware, the instructions are VERY difficult to understand. But once the tank is set up, it's quiet and bubbly near the top and has lots of room.

    • Okay tank, filter not great, many fish died
The size is nice, and the lighting works well (make sure to rotate it the right way). But the filter blows super hard, even if you close down the little tube. And the bottom part sucks in fairly hard. I had 2 zebra fish get stuck in it. We lost 2 goldfish and 6 tetra glofish. The zebrafish and 1 other black fish (not sure the kind) survived. I had the water tested multiple times and also tested and approved by PetSmart. I think the tank power is too intense. ... show more

    • FILTER DOES NOT WORKKKK

Filter does not work, tried everything but it seems its damaged or something. Looks great, easy to clean, space savy but for the price its not that nice since the filter (something basic) does not work.

    • Terrible set up instructions for filtration system.
Size: 4 Gallons
The reason I gave as many as 2 stars for this aquarium is because the tank itself is very cute and the perfect size. I have had aquariums most of my life so have set up many.This one is just for my molly's to give birth. However the filtration system is impossible to set up. I even went online for a video...cant get it set up. Resorted to ordering a pump and filtration system, so don't think you're actually saving money to get running. ... show more
